[ANGLÈS] Spatial Division Multiplexing (SDM) has arisen during the last years as the most promising technique to overcome the increasing necessity of capacity of the communication systems while avoiding the theoretical ...

In the present project, the effect of physical impairments induced by the transmission trough a flexgrid optical network, has been studied by means of numerical simulations. In particular, the frequency filtering effect ...

The OFDM technology has been highly studied/investigated in the telecommunications field but it is still a relatively new term in the optical communications. OFDM has been evaluated in various studies although the tolerance ...

[ANGLÈS] After the extremely fast growth over last two decades, single-mode fibers capacity is reaching its recently revealed fundamental limit, imposed by a combination of Shannon's information theory and fiber nonlinearities. ...

[ANGLÈS] This thesis consists in the design and implementation of a Visible Light Communications (VLC) system, based on an Arduino platform. The document describes the main features of this system, by describing how each ...

This project aims to investigate the impact of crosstalk in optical OFDM modulation under ideal conditions, i.e. without losses, phase noise or nonlinear effects. In order to get it we will analyze deeply how the OFDM works ...

We start by describing what SDM is, the problem at hand for it’s been considered and the different solutions it can provide. We focus on Multi - Core Fibers (MCF) as the favorite solution re garding SDM and ...

In a society where the need for communication is increasing every day, an improvement in spectral efficiency and faster data transmission methods are needed. This thesis analyses a new modulation, the Nyquist modulation, ...

Applying flexibility to the optical networks has become a hot topic in the optical technologies field. This proposal has some advantages but also considerable drawbacks that allow us to question if the use of these networks ...
